Instagram and Snapchat have removed the ability to feature Giphy stickers in their respective Stories over a racist GIF, according to a report by TechCrunch.

Lyauna Augmon, a Twitter user, posted a screenshot of the offensive GIF, tagging Instagram’s founder Kevin Systrom, asking for it to be taken down.

A Snapchat representative confirmed to TechCrunch, “As soon as we were made aware, we removed the GIF and have disabled Giphy until we can be sure that this won’t happen again… while we wait for Giphy’s team to take a look at it.”

In a statement to TechCrunch, Giphy admitted it was to blame for the issue.

“A user discovered an offensive GIF sticker in our library, and we immediately removed it per our content guidelines.

After investigation of the incident, this sticker was available due to a bug in our content moderation filters specifically affecting GIF stickers. We have fixed the bug and have re-moderated all of the GIF stickers in our library.

The GIPHY staff is also further reviewing every GIF sticker by hand and should be finished shortly.

We take full responsibility for these recent events and sincerely apologize to anyone who was offended.”

Giphy allows users to post content to their site, and their terms of service say that users aren’t allowed to post any content that is abusive, offensive, or vulgar.
